FIELD OF THE DISCLOSURE

The present disclosure relates to systems and methods for enhancing the accuracy of spatial location and rotational orientation determination of a wearable head-mounted display device while in a motion simulating vehicle.

BACKGROUND

Head tracking is known among virtual reality (VR) systems and augmented reality (AR) systems. However, VR and AR tracking systems assume a user is stationary (i.e., sitting down) or in a restricted space (e.g., a living room). If the user is in a moving vehicle (e.g., a car) and a VR head-mounted display device is head tracking the user's head, the tracking system may get confused with detected secondary motions of the moving vehicle. The tracking system fails to maintain a consistent reference point and therefore display of a virtual space to the user may be off. Furthermore, personal motion simulators may be expensive to obtain to use in conjunction with VR systems.

SUMMARY

The present invention is directed to utilizing simulated motion of a vehicle in addition to user motion of a VR head-mounted display device to enhance accuracy of determination of spatial location and rotation orientation of a head-mounted display device of a user. The determination may facilitate presentation of views of a virtual space to the user.

One aspect of the present disclosure relates to a system configured to enhance accuracy of spatial location and rotational orientation determination of a wearable head-mounted display device while in a motion simulating vehicle. The system may include one or more of sensors and hardware processors configured by machine-readable instructions. The sensor(s) may be configured to generate output signals conveying vehicle information. The vehicle information may characterize vehicle operations of a vehicle. The sensor(s) may be configured to generate output signals conveying user information of a user. The user information may characterize motion of a wearable head-mounted display device mounted on the user's head. The processor(s) may be configured to obtain presentation information.

Server(s) 102 may be configured by machine-readable instructions 106. Machine-readable instructions 106 may include one or more instruction components. The instruction components may include computer program components. The instruction components may include space component 114, spatial rotational determination component 116, presentation component 118, and/or other instruction components.

Space component 114 may be configured to obtain presentation information. The presentation information may define values of virtual space parameters. The virtual space parameters may characterize an instance of a virtual space including virtual objects.

The instance of the virtual space may comprise a simulated space that is accessible by the user and/or other users via a wearable head-mounted display device (e.g., wearable head-mounted display device 120, and/or other wearable head-mounted display devices) that presents the views of the virtual space to the user and/or other users. The simulated space may have a topography, express ongoing real-time interaction by one or more users, and/or include one or more objects positioned within the topography that are capable of locomotion within the topography. In some instances, the topography may be a 2-dimensional topography. In other instances, the topography may be a 3-dimensional topography. The topography may include dimensions of the space, and/or surface features of a surface or objects that are “native” to the space. In some instances, the topography may describe a surface (e.g., a ground surface) that runs through at least a substantial portion of the space (e.g., comprising at least part of a virtual terrain). In some instances, the topography may describe a volume with one or more bodies positioned therein (e.g., a simulation of gravity-deprived space with one or more celestial bodies positioned therein). An instance executed by the computer components may be synchronous, asynchronous, and/or semi-synchronous.

The instance of the virtual space may include virtual space content determined based on individual virtual space content associated with individual objects and the arrangement(s) of the objects, and/or other information. The space component may use the instance of the virtual space to facilitate presentation of one or more views of the virtual space to a user. The space component may use the instance of the virtual space to enable a user to interact with the virtual space. In some implementations, the execution of the instance of the virtual space may include the space component executing an instance of a game within the virtual space. The virtual space may include views of virtual objects. The virtual objects may include non-user characters, virtual items (e.g., virtual food, virtual weapons, virtual clothing, etc.), and/or other virtual content.

The above description of the manner in which state of the virtual space is determined by space component 114 is not intended to be limiting. The space component 18 may be configured to express the virtual space in a more limited, or richer, manner. For example, views determined for the virtual space representing the state of the instance of the virtual space may be selected from a limited set of graphics depicting an event in a given place within the virtual space. The views may include additional content (e.g., text, audio, pre-stored video content, and/or other content) that describes particulars of the current state of the place, beyond the relatively generic graphics. For example, a view may include a generic battle graphic with a textual description of the opponents to be confronted. Other expressions of individual places within the virtual space are contemplated.

Space component 114 may further be configured to obtain other information. Other information may include vehicle information, user information, and/or other information. The other information may facilitate determination of a presentation of one or more views of the virtual space to the user.

Spatial rotational determination component 116 may be configured to determine spatial location and rotational orientation of the wearable head-mounted display device. Determination may be with respect to a reference frame such that accuracy of the determination is enhanced with respect to only using the user information. Determination may be based on the user information and the vehicle information. Space component 114 may be configured to determine, based on the output signals, the vehicle information and/or the user information. Spatial location, as used herein, may refer to a geo-location of the wearable head-mounted display device 120, an elevation of the wearable head-mounted display device 120, seat in a car of the wearable head-mounted display device 120, area of a vehicle of the wearable head-mounted display device 120, and/or other measurements. Rotational orientation, as used herein, may refer to one or more of a pitch angle, a roll angle, a yaw angle, heading, pointing direction, and/or other measurements. In some implementations, the measurements may be specified with respect to the normal direction of the wearable head-mounted display device 120 relative to a surface on which it may be fixed at the base position. A reference frame may be a space through which vehicle 104 moves, vehicle 104 itself, or other reference frames.

FIG. 3 illustrates example rotational axes for a head-mounted display device on a user's head. Rotational axes for the head-mounted display device 304 of user 306 may include a yaw axis 310, a pitch axis 320, a roll axis 330, and/or other axes. Rotations about one or more of the yaw axis 310, the pitch axis 320, the roll axis 330, and/or other axes may define directions of view (e.g., viewing directions) for the head-mounted display device 300 (i.e., the user).

For example, a 0-degree rotation of the head-mounted display device 304 around the yaw axis 310 may correspond to a front viewing direction. A 90-degree rotation of head-mounted display device 304 around the yaw axis 310 may correspond to a right viewing direction. A −90-degree rotation of the spherical visual content 304 around the yaw axis 310 may correspond to a left viewing direction.

A 0-degree rotation of head-mounted display device 304 around the pitch axis 320 may correspond to a viewing direction that may be level with respect to horizon. A 45-degree rotation of head-mounted display device 304 around the pitch axis 320 may correspond to a viewing direction that may be pitched up with respect to horizon by 45-degrees. A 90-degree rotation of head-mounted display device 304 around the pitch axis 320 may correspond to a viewing direction that may be pitched up with respect to horizon by 90-degrees (looking up). A −45-degree rotation of head-mounted display device 304 around the pitch axis 320 may correspond to a viewing direction that may be pitched down with respect to horizon by 45-degrees. A −90-degree rotation of the spherical visual content 304 around the pitch axis 320 may correspond to a viewing direction that may be pitched down with respect to horizon by 90-degrees (looking down).

A 0-degree rotation of head-mounted display device 304 around the roll axis 330 may correspond to a viewing direction that may be upright. A 45-degree rotation of head-mounted display device 304 around the roll axis 330 may correspond to a viewing direction that may be rotated to the right by 45-degrees. A −45-degree rotation of head-mounted display device 304 around the roll axis 330 may correspond to a viewing direction that may be rotated to the left by 45-degrees. Other rotations and viewing directions are contemplated.

Referring back to FIG. 1, spatial rotational determination component 116 may be configured to, at specified points in time, determine spatial location and rotational orientation of the wearable head-mounted display device. The determination may be with respect to a reference frame such that accuracy of the determination is enhanced with respect to only using the user information. Determination may be based on the user information and the vehicle information. Specified points in time may include every n seconds, every n minutes, every n hours, every n measured distance traveled, every n motions of the user, and/or other specified points in time.

Space component 114 may be configured to determine a view of the virtual space. The view of the virtual space determined may correspond to the spatial location and the rotational orientation of the wearable head-mounted display device determined. The view of the virtual space determined may be enhanced such that when the user rotates his head while in a simultaneously moving vehicle, the view of the virtual space may correspond with the forces of the vehicle.

Presentation component 118 may be configured to effectuate the view of the virtual space determined. Effectuation may be via display 112 of wearable head-mounted display device 120.

In some implementations, the reference frame may be a space through which the vehicle is moving. Spatial rotational determination component 116 may be configured to determine the spatial location and the rotational orientation of the wearable head-mounted display device with respect to the space through which the vehicle is moving. The accuracy of the determination may, therefore, be enhanced with respect to only using the user information. Determination may be based on the user information and the vehicle information.

In some implementations, space component 114 may be configured to obtain the vehicle information. In some implementations, space component 114 may be configured to determine, based on the output signals, the vehicle information. Space component 114 may be configured to determine, based on the vehicle information, navigation information. As described above, the navigation information may include active navigation instructions of the vehicle and/or current GPS position of the vehicle such that future vehicle movements are known. Space component 114 may be configured to determine, based on the navigation information, the view of the virtual space. The view of the virtual space may correspond to, based on the navigation information, a space through which the vehicle is moving. Furthermore, the view of the virtual space may correspond to, based on the user information, the spatial location and the rotational orientation of the wearable head-mounted display device determined.

FIG. 6 illustrates an example of the system, in accordance with one or more implementations. User 606 may be in a car with active navigation instructions. The active navigation instructions may include that the car may be due to turn right on ABC Street, then left on DEF Road, and/or other instructions. Based on the determined GPS position of the car, it may be determined the vehicle is 200 feet from ABC Street. Space component 114 may be configured to determine, based on the navigation information determined, view 602 of a virtual space. The virtual space may correspond to the spatial location and the rotational orientation of the wearable head-mounted display device 604 of user 606 determined. It may be determined that user 606 is sitting in the second row of the car and far left seat and looking up and to the left. Determination may additionally correspond to the space through which the car is moving (i.e., turn on a road up ahead). Effectuation of presentation of view 602 of the virtual space, via the display of wearable head-mounted display device 604, to user 606 may correspond to user 406 seeing his virtual spaceship barely avoid virtual asteroid 608 above him by the car turning right.

By way of non-limiting example, the car's speed may be decreased to make the right turn on ABC Street. Effectuation of the determined view 602 of the virtual space, based on the vehicle information (i.e., right turn ahead, speed of the vehicle, deceleration of the vehicle), may correspond to, for example, user 604 seeing avoidance of the virtual asteroid 608 in slow motion.

Referring back to FIG. 1, in some implementations, the reference frame may be vehicle 104. Spatial rotational determination component 116 may be configured to determine the spatial location and the rotational orientation of the wearable head-mounted display device with respect to the reference frame. The accuracy of the determination may be enhanced with respect to only using the user information. The determination may be based on the user information and the vehicle information.

In some implementations, space component 114 may be configured to obtain the user information. In some implementations, space component 114 may be configured to determine, based on the output signals, the user information. The user information may define the GPS location of the user relative to the vehicle. Spatial rotational determination component 116 may be configured to determine, based on the user information and the vehicle information, the spatial location and rotational orientation of the head-mounted display device of the user relative to the vehicle.

FIG. 5, illustrates an example of the systems and methods, in accordance with one or more implementations. The vehicle may be cruise ship 510 in which user 506 is free to move throughout. A cruise ship may be divided into several decks in which people may access and contains boundaries (e.g., edges of the decks, employee only areas, adult only areas, etc.). The cruise ship may further be divided into areas (e.g., lower level pool, theater, arcade, etc.). Based on the user information and the vehicle information (i.e., deck information, access information, etc.), the spatial location of wearable head-mounted display device 504 of user 506 may be determined as Upper Deck 14 such that user 506 is outside, likely feeling the wind, and near deck boundary 512. Space component 114 may be configured to determine, based on the user information and the vehicle information determined, view 502 of a virtual space. The virtual space may additionally correspond to the rotational orientation of the wearable head-mounted display device 504 of user 506 determined. Effectuation of the determined view 502 of the virtual space, may correspond to the user seeing virtual characters 516 in a virtual helicopter 518 lifting off virtual edge 520 of a cliff to get away from zombie 522.

By way of non-limiting example, the user information may include spatial location of the user may be determined as in the arcade on Promenade Deck 11. Space component 114 may be configured to determine, based on the user information determined, a view of the virtual space. The virtual space may correspond to the spatial location (i.e., arcade on Promenade Deck 11) and the rotational orientation of the wearable head-mounted display device determined. Effectuation of presentation of the view of the virtual space, via the display of the wearable head-mounted display device, to the user may correspond to the user, for example, exploring an apocalyptic building.

In some implementations, the system may be coupled to individual vehicles. FIG. 2 illustrates a system to enhance accuracy of spatial location and rotational orientation determination of a wearable head-mounted display device, in accordance with one or more implementations. For example, the system may be communicatively coupled to individual vehicles and/or to components carried by individual vehicles, including but not limited to transceivers.

It should be appreciated that although components 114, 116, and/or 118 are illustrated in FIG. 1 and FIG. 2 as being implemented within a single processing unit, in implementations in which processor(s) 134 includes multiple processing units, one or more of components 114, 116, and/or 118 may be implemented remotely from the other components. The description of the functionality provided by the different components 114, 116, and/or 118 described below is for illustrative purposes, and is not intended to be limiting, as any of components 114, 116, and/or 118 may provide more or less functionality than is described.
